How to Calculate Hydroseeding Application Rates

Hydroseeding is an effective method for planting grass and other vegetation on large areas quickly and efficiently. However, to ensure the success of your hydroseeding project, it is important to calculate the correct application rate for your chosen seed and mulch mixture. Here are the steps you need to follow to calculate hydroseeding application rates:

Step 1: Determine the area to be hydroseeded
The first step is to determine the area of the site that needs to be hydroseeded. Measure the length and width of the area in feet and multiply the two numbers together to get the total square footage.

Step 2: Determine the seed and mulch mixture ratio
Next, you need to determine the ratio of seed and mulch to be used for the hydroseeding application. This will depend on the type of seed and mulch you are using, as well as the desired outcome of the project. Consult with your seed and mulch supplier to determine the appropriate ratio for your project.

Step 3: Calculate the amount of seed needed
To calculate the amount of seed needed for the project, multiply the total square footage of the site by the desired seeding rate in pounds per 1,000 square feet. For example, if the desired seeding rate is 5 pounds per 1,000 square feet and the site is 10,000 square feet, you will need 50 pounds of seed for the project.

Step 4: Calculate the amount of mulch needed
To calculate the amount of mulch needed for the project, multiply the total square footage of the site by the desired mulch rate in pounds per 1,000 square feet. For example, if the desired mulch rate is 1,000 pounds per acre and the site is 10,000 square feet, you will need 220 pounds of mulch for the project.

Step 5: Calculate the total weight of the mixture
To calculate the total weight of the seed and mulch mixture, add the weight of the seed and the weight of the mulch together. Using the previous examples, the total weight of the mixture would be 270 pounds (50 pounds of seed + 220 pounds of mulch).

Step 6: Calculate the application rate
To calculate the application rate, divide the total weight of the seed and mulch mixture by the total amount of water to be used for the hydroseeding application. For example, if you are using 1,000 gallons of water for the application, the application rate would be 0.27 pounds per gallon (270 pounds / 1,000 gallons).

By following these steps, you can calculate the correct hydroseeding application rate for your project and ensure the success of your hydroseeding efforts.
